Specification of Letters Patent.

Patented Aug. 29, 1911.

Application filed November 5, 1888. Serial No. 695,540.

To all whom it may concern:

Be it known that I, HENRY W. WINTER, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Machines for Setting Heel and Solo Protectors for Boots or Shoes, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object the production of a machine for setting heel or sole protectors for boots or shoes, such protectors being of metal bent or curved into substantially horseshoe shape in cross-section. Such protectors are driven into the material of the sole or heel in such manner as to leave the exposed or wear-resisting end of the protector substantially flush with the surface of the work, and such protectors are commonly made in two forms. One form of protector may be driven either end fore most into the work, as both ends are alike, while another form of protector has a flattened head end, a retaining shoulder extending around the exterior of the protector between its head and foot, and the foot or opposite end of said protector is beveled. The latter form ofprotector is preferable, inasmuch as it is held more firmly in the material of the sole or heel by reason of its shape and retainin shoulder, so that it cannot work loose an drop out, and whilethe machine forming the subject matter of my invention is adapted to set either form of protector, it is particularly adapted for handling and setting protectors of the second form referred to havin a head and a foot, as the respective ends 0 the protector may be termed, with. the exterior beveled in one direction. So far as I am aware such protectors in general practice have been set or inserted in the work by hand owing to the difficulty encountered in providing means for presenting such protectors with the foot end foremost to be driven into the work.

The various novel features of construction, arrangement and operation embodied in myinvention -will be described in detail in the following specification, and particularly pointed out in the claims.

Zll unih A of suitable construction, provided,

In my present invention, as will more fully appear hereinafter, I have made provision for the presentation and simultaneous setting of a plurality of protectors, and the mechanism is adapted to set the protectors for either a right or a left shoe.

Referring to Figs. 1, 2 and 3, I have herein shown the working parts of the machine as-mounted on an upright standard or 001- as shown in Fig. 1, with feet A to form a firm and extended base, the standard belng surmounted by a head A of suitable shape,

to provide bearings for the operative parts'.. The main shaft B is supported in bearings A A, on the head, and a'bracket or arm A respectively, said bracket being secured to or forming a part of the head, the shaft B at its forward end having a wrist pin (2, see Fig. 3, on which is mounted loosely a roll Z) for a purpose to be described. A pulley B is loosely mounted 01). the shaft and is adapted to be connected therewith at times by any suitable clutch mechanism G, and I have herein illustrated one form of the well known Horton clutch. The usual stop lug c is controlled by a detent c on the upper end of a lever 0 the opposite end of said lever being at times moved by a dog 0 fast on a rock shaft 0, the latter being provided with an arm a connected by a l1nk c with the treadle T, mounted on the base of the standard and normally elevated by a spring S", a spring 8 attached at one end to the lever c maintaining it in engagement with the dog 0 This clutchis adapted to connect the-shaft and the loose pulley B, while the shaft makes one revolution, and at the end of the revolution the clutch is released by the engagement of the stop 0 with the detent a; The pulley B has fast upon the inner end of its hub a bevel gear 03 in mesh with a similar gear d fast on one end of a worm d mounted in a bearing A on the head, the worm in turn engaging a worm gear d on a short shaft d, mounted to rotate in a bearing in the head and having fast upon it a gear at which meshes with a gear 03", secured to or forming part of a cam disk D provided in its outer face with a cam groove d", shown clearly in Fig. 4.

A hopper H is mounted on the upper portion of the head of the machine, said hopper comprising stationary upright ends it, it, between which is rotatably mounted, preferably on ball bearings as shown in Fig. 3,.

a cylindrical body if provided with an annular gear h in mesh with the gear 05 hereinbefore referred to, the interior of-the hopper bodyh being provided with suitable lifters it, see Fig. 4, substantially parallel to the axis of rotation of the hopper body and adapted to lift the protectors from the lower portion of the hopper and to discharge them onto asuitable receiver or shelf,

from which they pass to the elevators to be described, the elevators resenting the protectors to the upper en s of the raceways. The rear end wall it of the hopper is provided with suitable guides h, see Fig. 4, for a vertically reciprocable carrier, shown as a plate E having a depending arm E rigidly secured thereto and provided with a roller or other stud e", to enter the cam groove d", rotation of the cam disk D thereby efiecting the reciprocation of the carrier E. The end wall it is provided with a series of vertical slots h, five of such slots being herein shown to receive a corresponding number of elevators E", shown as thin plates set on edge and secured to the carrier E in any suitable manner, the elevators extending, as shown in Fig. 3, into the body of the hopper and reciprocating vertically therein by or through the described move ment of the carrier E, the upper edges e of the elevators being inclined toward the front of the hopper, as clearly shown in Fig. 3.

Referring now to Figs. 3 and 4 a receiver, shown as a casting of somewhat peculiar shape, is mounted within the hopper, said casting F comprising a series of upright separated walls f, alternating with theevators E and arranged quite closely to the "sides of the latter, the said walls having their tops stepped as at f" with the treads of the steps, as they may be termed, inclined frointhe back to the front end wall of the hopper, as best shown in Fig. 3, and below the stepped top of each wall the vertical face of the latter is provided with a second tier or series of steps f the tread port-ions f being parallel to the treads of the top, as best shown in Fig. 4 to form a series of recesses slot-ted at f, and in which the elevators rise and fall.

The protectors are carried by the.lifters h upward from the bottom of the hopper, and are discharged upon the walls and into the recesses of the receiver F, and the in clined treads of the steps serve to constantly turn and alter the position of the protectors as they are agitated and lifted from time to time by the elevators, to thereby prevent a number of protectors massing together in one of the recesses and simply rising and falling as a mass with the movements of th elevator.

Some of the protectors which are carried to the treads of the steps slide down the latter and against a guard plate Gr located in front of an opening 72, in the front wall of the hopper, the guard plate returning the protectors to the bottom of the hopper. This opening 12. in the hopper wall admits the upper ends of a series of raceways R, the latter being formed as thin metal bladelike pieces extended intov the hopper on edge, and at their broadened upper ends 7 resting on the casting F immediately in front, and closely adjacent the paths of movement of the outer ends of the elevators E", the lower ends of the upper sections being rigidly secured to a bracket A on the head of the machine.

As the elevators rise such of the protectors in the recesses between the walls f 'of the casting as are in proper position will straddle the elevators and will be lifted thereby, into position to slide from the ele-.

vators when the latter are in their uppermost position onto the adjacent ends r of the raceways, a dwell in the cam groove cZ maintaining the elevators stationary for a short time at the upper end of their strokes.

After the protectors have been delivered to the raceway, they move into position to be acted upon by a selecting device which is arranged to remove from the raceway such protectors as present themselves wrong end foremost, and while the selecting device is operating, a detent acts to hold the series of protectors above it stationary upon the raceway, while at the same time a let-ofi device is operative to form a stop or wall to prevent thepassage beyond it of a protector until the selecting device has been moved into operative position, the relative movement of the detent and let-ofi being such that one moves out of and into operative position again before the other moves into inoperative position, and vice versa. As will presently appear, the detent is so constructed as to form a guide for and diroot the movement of animproperly positioned protector as it is moved from the raceway by the selecting device. The let-0d also has an additional function, viz., to clear the raceway of protectors as it moves into operative position, provided the raceway below said Iet-ofi' should be filled, as shown in Fig. 12.

A box-like chambered or hollow casting K is attached to the front wall of the hopper the said casting inclosing the opening k in said hopper wall, and within and upon this casting I have arranged the selecting detent and let-off devices, the upper sections R of the raceways passing through the casting K to the bracket A, from which the second sections of raceways R conduct the protectors still farther on their path toward the drivers.

Referring now to Figs. 3 and 812 inclusive, the sides of the casting K are grooved to receive three adjacent slide plates M, N, and 0, arranged in the order named from rear to front and substantially at right anles to the raceway sections R. The plate F1 is cut away centrally to leave top and bottom bars m, m, respectively, the latter having a depending foot m to enter a slot in a boss K and engage the periphery of a cam Mi fast on a short shaft K" mounted their inner faces and in fixed bearings in said boss, the upper bar m being provided with a series of undercut, upright grooves, as shown in Fig. 9, to receive each a sliding detent member in, shown separately in Fig. 9*, the lower end of the detent being concaved as at m to rest upon one of the protectors P when the detent is in operative position, as shown in any one of Figs. 10, l1 and 12. A stud m in the back of each detent enters a slot or recess m in the top bar m, to limit the movement of the detent relative to its carrier bar or support m, while a suitable spring 8 fast on said supporting bar rests at its free end on the top of and normally depresses the detent, thus compensating for slight variation in the sizes of the protectors. The series of detents m are arranged in their support m above the series of raceways R, as clearly shown in Fig. 8, and in this figure the detents are elevated to permit the free passage of the protectors beneath them. Suitable springs S, fixedly attached at one end to the side walls of the chamber K and at their other end to pins or studs projecting from the frame M, serve to depress said frame and maintain the foot m in engagement with the periphery of the controlling cam M". Immediately in front of and adjacent" 1e plate M, a second plate N is mounted to slide in the casting K, said plate being U'shaped and having a depending foot 17. to travel upon the .periphery of a 'cam N fast on the shaft K", springs S, Fig. 1, depressing said plate and maintaining its foot in engagement with its controlling cam. A series of upturned fingers a are secured to the plate N, the endmost fingers being shown as single in Fig. 8, while the intermediate fingers are made double for convenience in construction, said fingers being beveled at their upper corners as at n, the bevels of two cooperating fingers being opposite and corresponding to the external bevel of the foot or lower end of the protector, as shown in Fig. 9, so that when a protector presents itself with its lower end or foot foremost, the fingers as they rise will ass at each side of the beveled foot, as s own in full lines in Fig 9, the protector P being therein illustrated as properly positioned to pass down the raceway. If, however, the protector should present itself head end foremost, as shown by dotted lines at P, Fig. 9, the bevel of the protector will be opposite to the beveled corners of the fingers, and as the latter rise the fin ers will engage said protector and lift it fiom the raceway.

Referring now to Fig. 9 the detent is shown as provided on its outer face with two wings 'or lips m outwardly beveled on rojecting, as shown in Figs. 10, 11 and 12, ust back of the path of movement of the fingers it. When the fingers which form a selecting device en counter a properly positioned protector, they normally pass at each side thereof as described, but if there should be any slight fin or enlargement of the protector, the fingers would tend to lift-or tip it, and to prevent this the wings m of the detent, by their engagement with the head of the pro tector, hold it down against such upward movement of the selecting fingers so that it will not be removed from the raceway, as at P, Fig. 9. On the other hand, when a protector, as P, is improperly positioned), it will be seen, by reference to Fig. 9, that the bevel of the wings m then corresponds to the bevel of the foot of the protector, and acts as a guide for the latter when it is lifted from the raceway by the selecting device, and serves to direct it forward toward the front inclined wall of the casting K, from which it travels by gravity back to the hopper.

In Fig. 10 the detent is shown in engagement with an improperly positioned protector P, while the selectlng device has moved into operative position and consequently has not disturbed the other of the protectors P which is properly positioned and ready to travel along the raceway as soon as the let-off is withdrawn to permit it.

The let-off mechanism comprises essentially a second U-shaped bar 0 adapted to slide in the side walls of the casting K and provided with a depending foot 0 tobear against the periphery of a cam O fast on the shaft K", springs S connected at their free ends with the plate 0 serving to depress it and to maintain the foot against the cam. The ,said plate has attached to its transverse portion a series of upturned lugs 0 arranged in pairs, as clearly shown 1n Figs. 8 and 9, said pairs of lugs being so located relative to the several racewa'ys that when the plate 0 is raised, the said lugs will slide upward at each side of the raceway and act as a stop to prevent passage of a protector through one of the openings k" in the front wall of the casting -K.

In Figs. 10 and 12, and in Fig. 8, the letoif device is in operative position, while in Fig. 11 it is retracted into inoperative position, so that the lugs 0 are below the path of travel of the protectors. The three cams M", N*, and 0 are of such shape, see Fig. 8, and so set relatively to each other that in the rotation of the shaft K", supposing the parts are in the position shown in Fig. 10, the endmost and properly positioned protector shown therein will pass down the raceway as soon as the let-off lugs 0 are depressed.

In Fig. 11 the let-ofi' for one raceway is shown in inoperative position and the endmost protector has started-and isjust about to pass through the opening in the front wall of the casting K, While the detent m for such raceway still holds stationary the endmost protector of the series thereupon. Further rotation of the shaft K operates to move the let-ofl' lugs into operative position and to withdraw the selecting device, and when the latter is in inoperative position the cam M operates to raise the detent device and release the series of protectors, so that the endmost one will slide down into position above the path of the selecting device, and as the latter rises, the detents are again lowered into operative position as before. Now, as has been described, the protector which is in the path of the selecting device will be engaged by the latter or not, according to whether said protector is head end or point end foremost. The let-off mechanism has an additional function, viz., to clear the raceway of the down-moving protectors if it should happen that the raceway beyond the said let-ofi mechanism should be full, and referring to Fig. 12, it is supposed that the lower part of the raceway is so loaded with protectors that the latter have backed up, as it were, intothe position shown. Under such circumstances tlie-l t-ofl lugs as they rise will engage that prote tor which is located -on the raceway above them, and will lift and tip it from the raceway, to fall back again into the hopper,

a protector being shown in F i 12 as tipped and just about to be thrown from the raceway. This function of the let-off mechanism will be called into play Whenever the raceway is crowded, and by its action prevents any improper presentation of the protectors to the act-ion of the selecting and letoff devices.

The shaft K" has fast thereon a bevel gear is in mesh with the bevel pinion 70 on a shaft 10 provided with a gear 76 which engages and is driven by a ring gear 71 secured to the hub of the cam disk D.

The front wall of the chamber K is shown as provided with deflectors to deflect the protectors laterally from a raceway when they are removed therefrom, either by the selecting device when they are improperly presented, or by the let-off lugs 0 when the latter act to strip the raceways. These deflectors are shown as beveled blocks in" secured to the inner face of the front wall above and at one side of the several raceways, the end deflectors 10 and one other, as 70 being shown single, while the deflector I0 is made double, owing to their use with five raceways. Each end deflector turns a protector from its adjacent raceway into the space between such raceway and the next adjacent inner one, while deflector 70 turns them into the space between the center raceway and the second one from the left hand end, Fig. 8. The double deflector k takes care of protectors removed from the central raceway and the one next it on the right, viewing Fig. 8, so that by the use of the deflectors protectors which have been removed from the raceways cannot again fall 11 on them, but pass from the bottom of the c amber K back into the hopper.

The raceway sections R are enlarged or beaded along their upper edges as at r, Fig. 14:, to prevent the protectors from dropping off as they travel along to the vertical or substantially vertical sections R of the raceways.

are in alinel'nent with the upper sect-ions R and also with the upper ends of the lower upright sections R the shelf of the bracket A having openings 5 therein, see Fig. 3, for the passa e of the protectors.

The head 2 is vertically grooved at A", Fig. 3, to receive a plungerB having a transverse groove in its rear face to be entered by the roll Z) on the wrist pin'of the main shaft B, whereby said plunger will be reciprocated as the shaft rotates, the highest position of the plunger being shown in Fig. 3. An overhanging projecting portion 1) of the plunger has detachably connected thereto as by a dove-tailed groove, see F ig.

2, a driver plate I) in which are secured a series of depending drivers 5', the plate I) being made removable so that gangs'of differently positioned drivers may be readily applied to the machine. The shape of the drivers is best shown in .Fig. P, said drivers corresponding substantially in shape and size to the heads of the protectors, the path of movement of the drivers being herein shown as at the rear of the lower ends of the raceway sections R The head A is extended forwardly to form arms A below and at the sides of the drivers, and grooved on their inner faces, as shown in Fig. 2, to receive a positioning or pressure block F 4 which also forms'the fixed rest for the work during the insertion of the protectors, and for convenience in positioning the boot or shoe when the protectors are to be inserted in the heel thereof, I have herein. shown a curved guide plate F 5 attached to the underside of the block F to receive and position the heel. The block F 4 has a series of driver passages f therein, see Figs. 3 and 5, of such shape and size as to permit the passage therethrough of the protectors as they are being driven into the work, each passage having a central rib f therein to guide and position the protector while being driven. The top of the block F is recessed as at f, Figs. 6 and 7, to receive a transferrer shown as a peripherally toothed plate T mounted to rotate on a boss 1", rejecting from the block F, the teeth t of the transferrer engaging the teeth of a gear 25 mounted on a screw stud 6 The sections It are secured at their ends to the brackets A, A and of course tion to receive protectors from the raceways to be subsequently driven into a left boot or shoe when the transferrer is restored to midway positlon, as shown in said Fig. 5. If

the handle is swung in the direction of the arrow 12 into the position shown in Fig. 7, the transferrer is then ready to receive protectors to be driven into a right boot or shoe.

For the purpose of yieldingly detaining the handle and transferrer in each of the three positions thereof a detent-device is provided, which, as shown in Fig. 6, comprises a pin 6 seated in a hole bored in head A beneath segmental gear 15 and acted upon by an expanding spiral spring that is compressed in said hole beneath. the pin, a series of holes t t, it, being made in the under side of the segment-gear to receive the acting end of the said pin. These holes last-nftntioned are so disposed that in each of the three positions of the parts one of the holes is presented in position to receive the acting end of the detent pin. Thereby the handle and transferrer are held from accidental turning movement. The acting end of the pin is rounded so that upon the application of sufiicient power to the handle tending to swing the same the pin will be forced downward into its hole, permitting the segment-gear to be turned.

A plate F is attached to the top of the block F and near its outer end is raised as at f to form a suport for the lower ends of the raceway sections R the latter approaching within a short distance of the exposed upper face of the transferrer T. The position of these raceways is shown in Fig. 5, wherein they are indicated in section on the line m -w see Fig. 2. Inasmuch as the back end of a heel is not usually a true circle, the raceways R are not arranged all on the arc of a circle, as will be apparent from Fig. 5, the central raceway being set in from the are on which the other four raceways are placed, the center raceway being called into play whether the shoe be a right or a left.

As shown in full lines Fig. 7 the transferrer T has five holes 15" therein, shaped to receive protectors as they pass from the lower ends of the raceways, the protectors being held in the holes or pockets, during the, partial movement of the transferrer by the top of the. block F, but to keep protectors in place until the transferrer has properly positioned them above the driver passages f in the said block, I have provided a series of detents shown as slides f mounted in the transferrer and movable toward and from the pockets t", and normally held in retracted position by suitable springs .9 the springs resting against upturned lugs f on the de tents. The plate F 6 is provided with a cam shelf f shaped to act upon the lugs f as the transferrer is moved from loading into driving position, to move the detents one after another into engagement with the protector in the adjacent pocket, and to maintain by slight frictional pressure such protector pressed against the inner pocket wall.

until the descent of the drivers carries the protectors from the pockets through the driver passages and into the work. Commonly three protectors are driven into a heel and when loading for a right shoe, as in Fig. 7 the three foremost pockets of the transferrer in Fig. 7 such being at the right hand side in Fig. 5 will be located beneath and to receive each a protector from the three right hand raceways, viewing Fig. 2 or Fig. 7

The support 1 is provided with spring fingers f located adjacent and at the inner side of the two raceways at each side of the center, said fingers serving to hold the endmost protectors on the raceways after the transferrer has begun its movement from loading into driving position. When the transferrer moves into loading position, pins f are moved into engagement with the spring fingers f adjacent the two endmost raceways which are to deliver protectors, and such fingers are moved away from the protectors held by them, to permit free passage of the former down the raceways and into the pockets of the transferrer.

Inasmuch as the central raceway is to dc"- liver a protector each time whether the shoe be a right or a left, and because of the location of said raceway relative to the pockets of the transferrer, it is unnecessary to provide it with a stop finger because one or the other end pocket of the series in the transferrenwill always be brought beneath the central raceway when the transferrer is in loading position.

In Fig. 7 the position of the pocket 25" for driving is shown in dotted lines, and in Fig. 5 the transferrer is shown in full lines in driving position, the guides f in the driver passages being also shown through the open pockets, the upper ends of said guides being preferably beveled as at 15, Fig. 5, to facilitate the entrance of a protector into the driver passage.

It will be obvious from the foregoing description that the protectors remain in the transferrer from the time they pass there-to from the raceways until they are positively, pushed out of the transferrer by the impact of the descending drivers, and as soon as they thus leave the transferrer, they pass immediately through the driver passages and into the Work.

The work support is shown as a spindle W having attached to its upper end a suit ably shaped block W, to enter the heel end of and support the boot or shoe, the lower end. of the spindle being threaded as at W Fig. 3, to enter a threaded plunger W", vertically movable in a bearing a secured to or forming part of a slide W mounted in a suitable guide A, attached to or forming a part of the standard A, the slide having an upturned arm to at the rear of the spindle and slotted at w to receive a stud or pin m projected rearwardly from the spindle to prevent rotation of the latter when the plunger W is reciprocated. The lower end of the plunger projects beneath the slide V and rests upon a cam W loosely mounted on a shaft 10 having its hearings in the two parts of the guide A, as shown in Fig. 2, said shaft being extended through the disk- ]ike hubs 'w of two arms 'w connected by a. suitable link 'w with an ear 6 on the driver actuating plunger B The hub of the cam V is as shownin Fig. 2 located between the djsk-like hubs w and the latter are provld'eg with sleeve-like extensions 01;, which proj ct through and slightly beyond the bearing portions of the guide A. The shaft 10 is provided with a head as 18 at one end, and at its other end is threaded to receive a nut 20, so that by tightening the nut 20, the pressure of the disk hubs 'w upon the hub of the cam W may be varied according to circumstances.

Now, when the driver plunger B desc'ends, the disk hubs w will be turned in the direction of the arrow 25, Fig. 3, and by a frictional engagement with the cam will rock the latter to act upon and elevate the plunger W, and thereby raise the work toward the fixed heel support or pressure block F, and this relative movement of the Work support and pressure block will continue until the heel has been compressed to a predetermined point, after which the continued descent of the driver plunger B will operate only to still further rock the arms 11;" and their disk hubs w". When the driver plunger rises the disk hubs will, by their frictional engagement with the cam W move the latter in the opposite direction, to permit the descent of the plunger W until the cam strikes a fixed stop a on the guide A. By varying the friction between the lifting cam W and its actuating devices, the amount ofpressure to which the heel is to be subjected may be varied, and after the desired pressure is attained the heel may be maintained under such pressure while the protectors are driven thereinto. The height and density of the heel both operate to de termine the point at which the cam W will cease to elevate the spindle W. Variations in the heights of heels are provided for by adjusting the spindle W up or down in its plunger by means of the screw threaded socket therein.

Several raceways herein shown are made in sections principally for convenience in construction and adjustment, and it will be obvious that said raceways may be made continuous from one to the other end thereof. However, by making the raceways or certain thereof in sections, and particularly the lower ends thereof, I am enabled to readily use different gangs or numbers of raceways without dismantling the entire length of the raceway. So too, while I have shown a plurality of raceways, and have devised the machine to set a plurality of protectors simultaneously, it will be obvious that one protector at a time may be set by simply throwing out of operation all but one of the raceways, or indeed by merely leading one raceway into the hopper.
